Abstract
An optical Harr wavelet is created using a magneto-optic spatial light modulator (MOSLM). Two methods of controlling wavelet dilation are explored: (1) an aperture positioned in front of a binary modulated MOSLM; (2) spatial filtering of a ternary modulated MOSLM. Segmentation is performed through Vander Lugt correlation of a binarized image with the optical wavelet. Frequency-plane masks for the correlation process are generated using thermal holography.Keywords
